By way of summation and review, display apparatuses may be replaced byportable flat panel type display apparatuses.

It may be not easy to improve durability of portable flat panel typedisplay apparatuses due to difficulties in manufacturing processes, forexample, difficulties in manufacturing the portable flat panel typedisplay apparatuses to have a certain thickness. For example, portableflat panel type display apparatuses may need to be flexible according toan intention of a user or during manufacture, for example, may need tobe bent or folded. However, it may not be easy to manufacture durableportable flat panel type display apparatuses while obtainingflexibility.

As described above, according to one or more exemplary embodiments, adisplay apparatus may improve convenience of a user.
